Gabbroic rock that contains between 0 and 5 percent quartz and no feldspathoid mineral in the QAPF fraction. Includes rocks defined modally in QAPF Field 10 as gabbro.Note that this category includes gabbro (sensu stricto) of LeMaitre et al. 2002, but is broader, including the other rock types defined by orthopyroxene-clinopyroxene-olivine-hornblende mineral ratios.gabbroLeMaitre et al. 2002
